Overview

This type of fiber optic inertial unit has the advantages of small size, light weight, low power consumption, and high accuracy. It contains eight points of vibration reduction and can meet the application scenarios of large impact and large vibration. It can be used to design pure strap down and meet the needs of new unmanned platforms, water/torpedo weapons, as well as land, airborne, and missile weapon platforms for small size and high-precision inertial unit equipment. It has the dynamic measurement function of carrier angular motion and linear motion information.
